Go Power GP-PWM-10 User Manual page 8

Wire type is recommended to be a
stranded copper UV resistant wire.
Wire fatigue and the likelihood of a loose
connection are greatly reduced in stranded
wire compared to solid wire. Wire gauge
should be able to sustain rated current and
minimize voltage drop.
Wire Strip Gauge
You will find a strip gauge diagram on the
back of the GP-PWM-10, which helps you
to strip your wires to the correct length.
Insert wire into the concave slot of the
strip gauge until it meets the back of the
strip gauge slot. Mark the length of wire
from the back of the strip gauge slot to the
edge of the controller with a pen or your
finger and strip all wires to be connected to the controller to this length.
Suggested Minimum Wire Gauge
(Cable length 25 ft. max. from solar array to battery bank)
50 Watt Solar Module
80 Watt Solar Module
95 Watt Solar Module
110 Watt Solar Module
125 Watt Solar Module
160 Watt Solar Module
Terminal Screw Torque
IMPORTANT: Identify the polarity (positive and negative) on the cable used for the
battery and solar module. Use colored wires or mark the wire ends with tags. Although
the GP-PWM-10 is protected, a reverse polarity contact may damage the unit.
Wiring the GP-PWM-10. Wire the GP-PWM-10 according to the wiring schematic
in Section 6. Run wires from the solar array and the batteries to the location of the
GP-PWM-10. Keep the solar array covered with an opaque material until all wiring is
completed.
3. Torque all terminal screws to 16 inch pounds (1.8N.m).
C onnect the battery wiring to the controller first and then connect the battery wiring
to the battery.
IMPORTANT: Always use 10A fuse circuit protection on the positive conductor
attached to a battery.
